Fixed my misfire instantly, real or counterfeit though???
I had Cylinder 3 misfire, swapped 3 and 1 coil packs and misfire instantly move from 3 to 1. So i assumed it was the coil pack. So after replacing the coil pack misfire was still there. Next, replaced all four plugs with these mysteriously looking/flashy denso box plugs. Well, misfire is completely gone even with original coil pack that I initially replaced. I don't know but the misfire is gone completely and now I'll sit and wait to put some miles on these new plugs to see how they hold up after 5, 10, 15 thousand miles. Hey Denso, strategically mark and identify your plugs so the public can easily spot your real and the counterfeit fakes out there potentially fking up customers engines.

Awesome Spark plugs made her purr like a kitty kat!
Canister purge solenoid + fuel filter + fuel pump strainer bag + new air fuel mix sensor + these spark plugs to a 220k camry that nobody ever did a thing to and gave to me. I can hear every piston firing perfectly (I modified my exhaust for more HP free flowing the mufflers restrictor plates so its basically honey combing and a baffle. ) Sounds great I love thhe pep that was added from these fixes to my camry. Thhe fuel filter and pump strainer bag fixed all my high idle problems and jerky acceleration. Listen for ticking near the air filter and put ur hand on the box near it with only 2 smaller tubes attached. If its knocking the canister solenoid is letting air into your engine running it hot and will knockout your mix sensor.

Works well w/ Plasma III electronic ignition
Go these for use as the top plugs in an Lycoming O-320 engine. These plugs work well with the Light Speed Plasma III electronic ignition module.
